Oxidized Siding? Clean and Prevent To Restore Like New!

Siding Oxidation-How To Clean

The exterior of your house can be just as important to its appearance and longevity as the interior.

Oxidation, or fading, on painted and non-painted surfaces such as:

  • Hardi Plank,
  • Stucco,
  • EIFS,
  • Vinyl siding
  • Metal, Aluminum siding, Painted Metal Roofs, Garage Doors

occurs when Ultraviolet Light breaks down the binders in the paint or surface releasing pigments. The oxidation may also be caused by neglecting proper maintenance as well other causes which may include acid rain from car exhausts.

If you’re noticing your exterior walls looking a little dull, that’s not necessarily just because of the weather. If you’ve been keeping up with things like power washing and sealing and making sure there are no side-by-side seams on windows or doors that might trap moisture, then it’s probably oxidation.

Most often the South facing walls receive the most sunlight and are therefore affected the most by oxidation. If algae grows on your home, it is most prevalent on the North sides of the home- which receives the least amount of sunlight.

How do I know if my house is oxidized?

Homes are prone to oxidation and fading. It happens to all surfaces, just some quicker and more degrading than others.

Luckily there are a few ways you can tell whether your home’s surface is suffering from oxidation and fading. One way to spot this type of damage is visual inspection; surfaces will look dull and have an uneven or chalky appearance.

Another way to find out whether your house needs help with oxidation is through tactile inspection; gently rub a damp rag or your dry hand over the area in question. Make sure to do this is an inconspicuous area, if you do not plan on cleaning immediately, as you will see the clean area left behind.
